Fusible Resistor

In WWF series, resistors up to 5W, the resistance value is colour coded with 3 bands plus a tolerance band. An additional white band indicates that the resistor is fusible.

Can I replace fusible resistor with normal resistor?

For obvious reasons, one cannot be replaced with the other. If your resistor is not of the same variety, complement it (in series) with an appropriate fuse.

What are the 5 types of resistors?

Types Of Resistors

• Thermistors.
• Varistor Resistors.
• Photo Resistor or LDR (Light Dependent Resistors)
• Surface Mount Resistors.

Can we use resistor as fuse?

A resistor can be used as a fuse. A fuse can be used as a resistor. There are even fusible resistors, which act as a resistor with a definite value but they also act like a fuse on overcurrent. A resistor limits current by its value of resistance measured in ohms.

What is a fusible resistor used for?

The main function of a fusible resistor is to restrict the inrush current flow. So this resistor is used as the overcurrent component within the charger or power supply circuit that can have 10ohms of resistance. This circuit is used to protect over current & restrict inrush current.

What is a zero ohm resistor used for?

Zero ohm resistors are the perfect remedy to 'magically' route a single layer board. Rather than making holes and turning the PCB into a double-layer structure, you can route a trace between the pads of a zero ohm resistor. These resistors are then assembled along with other components during the manufacturing process.

Can you replace a resistor with a higher ohm?

Sometimes you need a resistor with a value you don't have in your kit. Instead of ordering and wanting for a resistor with a value you need you can change the resistance of a resistor by using another resistor or many. By installing resistors in a parallel or series circuit you can change the value in Ohms.

Can resistors catch fire?

Overloaded Resistor The resistance value can shift permanently, the lifetime can be significantly reduced, or the resistor is completely damaged resulting in an open circuit. In extreme cases the excessive power can even melt or catch on fire.

Can I use normal resistor instead of SMD resistor?

Yes. Just make sure you use the same resistor value with a power rating equal or greater than the smd part (which should be easy) and bend the leads to fit the solder pads of the smd part and solder it in place after removing the smd part.

What are the 4 types of resistors?

Types of Resistors

• Fixed Value Resistors. These are the predominant type of resistor configuration, and as the name suggests, they have a fixed resistance value.
• Variable Resistors. ...
• Resistor Networks. ...
• Carbon Film Resistors. ...
• Metal Film Resistors. ...
• Wirewound Resistors. ...
• Metal Oxide Resistors. ...
• Metal Strip Resistors.

What are the 3 types of resistor?

There are 3 main types of resistors based on their composition: carbon-composition resistors, carbon-film resistors, and metal-film resistors.

What is the most common type of resistor?

Resistor Types

• The fixed resistor type is the most common resistor.
• There are several variable resistor types, their general property is that the resistance value is adjustable. ...
• Thermistors are resistors of which the resistance changes significantly when the temperature changes.

What's the difference between a fuse and a resistor?

A fuse is a wire that breaks when a certain current passes through it. a resistor is a component that adds electrical resistance. a resistor limits the current by its resistance value measured in ohms. a fuse limits overcurrent damage by opening the circuit above a certain current value.

Is a car fuse a resistor?

A fuse is typically a metal wire strip that melts or burns when too strong a current passes through it, thus interrupting the flow of electricity and breaking the circuit to a given device. A car has many such fuses to protect its various electrical components from high voltage occurrences.

What can replace a resistor?

Can this resistor be replaced by a wire or fuse?

• Replace the resistor with a wire. That means basically no resistance and much more current flow in the close-by components.
• Replace the resistor with a fuse. We can calculate the appropriate current (230 V at 15 ~ 16 A) and have it soldered.

Do fuses have high resistance?

Assertion :Fuse wire must have high resistance and low melting point. Reason: Fuse is used for small current flow only.

What should the resistance of a fuse be?

If the reading is between 0 and 5 Ω (Ohms), the fuse is good. A higher reading indicates a bad or degraded fuse.

What is an SMD resistor?

A surface mount resistor is a tiny rectangular ceramic body with silver conductive edges on either end. Also referred to as surface mount technology, an SMD resistor offers advantages in saving space on printed circuit boards (PCBs). It features the resistance value code printed onto it, where there is space.

Does current flow through a 0 ohm resistor?

A zero ohm resistor can't restrict the flow of current.

Is a zero-ohm resistor the same as a wire?

A zero-ohm link or zero-ohm resistor is a wire link packaged in the same physical package format as a resistor.
